SOURCE: How do you remove the impeller

Take off the back of the motor, put a wrench on the shaft and turn the impeller by hand to loosen. It may be reverse threaded.

SOURCE: How do I remove the wet end of the pump from the

Take the screws off the outer cover fo the wet end. That will expose the impeller.
At the other end of the pump is a small metal cap in the middle. Pry that off with a screwdriver. That reveals the shaft of the motor which has a slot in it. This allows you to hold the shaft still with a large screwdriver.
While someone holds the shaft with a big screwdriver, you rotate the impeller counter clockwise to unscrew it off the motor shaft.
In my case the impeller was so caked onto the shaft with rust that we could not loosen it. We broke the impeller and still could not unscrew it. The screwdriver keeps jumping out of the slot in the shaft.
So the next step was to take the shaft out of the motor. On the far end of the motor are 4 small looking bolt heads. Undo those. They go right through the motor into the 4 legs of the wet end.
Stand the motor up with the wet end up. Pull hard to pull the wet end motor cover off the motor and you will then have the wet end and armature of the motor in your hands. Heavy.
Place some wood into a large vice and then grip the big silver part of the armature in the vice. Then unscrew the impeller.

The pump has been louder for a couple of weeks and after I stopped it to clean the spa filter, it won't start. Sounds likes it's seized


I had that happen when the spa was off for 10 days. I took the pump and wet end out, and managed to turn the shaft to free it. It has rusted up in place.
6 months later it started the loud noise and started getting worse - the motor bearing at the wet end was seizing up. I replaced motor and wet end just in time.

Need to change out bearings


You will need a 7/16 inch open ended wrench, a bearing puller, a phillips screwriver, a 12" peice of metal electrical conduit, and the bearings.
dismantle wet end of pump down to the impeller. Remove the shaft cap at the back of the motor(small circular cap in back). use 7/16" wrench to hold the shaft under the cap whiile spinning the impeller counter clockwise untill impeller is off. using a 1/4" hex driver remove the 4 through bolt located at the rear of the motor. seperate end caps on motor housing to access the bearings. use puller to remove. use the 3/4" conduit to tap new bearing into place. Reassemble unit.

Make sure you have an o-ring kit for this pump first

How do i remove impellor


The impeller in my 4 HP, 2-speed Waterway Executive High Performance 56 pool & spa pump has a brass coupling embedded in the back side. This coupling can be unscrewed from the motor shaft by keeping the shaft from rotating while turning the impeller in the reverse direction. Then the seal can be tapped out.
